Abstract: A signal control system for controlling the level of color signals to modulate the density of the electron beams in a color cathode ray tube having an array of phosphors that emit light of different colors, and in which at least one of the phosphors has a luminosity saturation characteristic that is different from the others. The system includes means to limit the peak signals applied to control the beam that strikes the phosphor least subject to saturation, the purpose being to prevent that phosphor from being excited beyond the level at which the other phosphors can maintain a balanced degree of luminescence.

Abstract: A vertical deflection circuit which has an output stage formed as a single-ended push-pull amplifier connected to a first voltage source through a unidirectional element and also connected through a switch device to a second voltage source supplying a voltage with an absolute value larger than the absolute value of the voltage of the first voltage source. The switch device is controlled to have the conductive state only in the retrace period and the output stage is supplied with the voltage of the first voltage source in the trace period and with the voltage of the second voltage source in the retrace period, whereby the output efficiency of the circuit is increased.
